Brass Vessels

 

Brass is an alloy of copper and zinc, if you want to know more about brass then your at right place . Here you will be learning about the history of brass, types of brass, composition of brass, color of brass and properties, industrial application of brass.

    Brief history of brass.

    Metalworkers from ancient days were skilled enough to recognize the difference between zinc ore and tin ore. But they were failed to understand that zinc was a metal.

    Until 1746, Andreas Sigismund Marggraf (1709-1782), a German scientist, identified zinc and determined its characteristics. 

    The process of mixing metal copper and zinc to form brass was patented in England in 1781.

    The earliest brass was called as calamine brass and historically it was also referred to as yellow brass.


    What is the Composition of brass?

    Brass is an alloy of copper and zinc. It mainly consists and also some other metals like lead, tin, iron, aluminium, silicon and manganese are added to produce more unique combinations of characteristics

    Different grades are available in Brass.

     • Alloy 230.

    Popularly known as red brass, it is more stronger than yellow brass, commonly used in the making of jewelry, decorative parts and also used in sprinklers.

    • Alloy 260. 

    Also known as cartridge brass, and also it offers great resistance to corrosion.

     Alloy 260 demonstrates good cold working properties. It is widely used in ammunitions, automobiles, fasteners, and hardwares etc.

    • Alloy 272.

    This alloy is often referred to as yellow brass—consists of 33% zinc. It is suitable for use in industrial and architectural applications.

    • Alloy 330. 

    Brass Alloy 330 is suitable for the process where some degree of machinability is necessary. It contains minute lead content sufficient for cold-working and is commonly used to produce Tubes .

    • Alloy 353.

     Alloy 353 is also popularly known as clock brass. This alloy is very easy to machine and often used in the making precision components, like clock and watch parts, nuts, gears, door hardware because of its excellent machinability.

          • Alloy 360.

     Also referred to as free cutting brass, this alloy is that the commonest sort of brass.

     It exhibits excellent machinability and formability, it consists of minute quantity of lead because of this property it can be easily cut and shaped into our requirement also as suitability for soldering and brazing operations.

     It commonly finds applications within the manufacture of hardware components, fittings, valves, and fasteners.


    • Alloy 385.

    Also known as architectural bronze alloy, this alloy is majorly used for construction & architecturing, and also in the making of ornaments. Alloy 385 is available in a wide variety of extruded & drawn shapes such as angles, channels, square tubes, handrail moulding & etc.


    • Alloy 464.     

    Alloy 464 (or naval brass) it offers a higher amount of resistance to corrosion from seawater across a wide range of temperatures.

     Also, it offers good strength and some degree of machinability. It is typically used in the making of marine equipment’s , wear plates, fasteners, condenser tubes etc.


    Different Colors brass.
    Brasses are available in a variety of colors, mainly yellow, gold, brown, silver based on different chemical compositions.


     Popular Types of brass.

    1.Naval Brass: 1%Sn with 60% Cu, 39% Zn 

    Tin improves corrosion resistance – used in contact with sea water
    Propeller shafts, valves, and impellers.

    2. Forging Brass: 60% Cu, 38% Zn, 2% Pb.

    •Offers Best hot working properties.

    • Using For hardware and plumbing parts.

    3.Cartridge Brass: 70% Cu 30% Zn.

    • High strength, ductility.
    • used for cartridge and shell cases of rifles.

    Properties of brass.

    1.Tensile strength is great.

    2.Yield strength of brass is from 250 to 500 Mpa.

    3.Brass metal alloys offer excellent resistance to corrosion.

    Because of Brass’s this property plating or powder coating is not required.

    4.Offers great machinability.

    5.Slight reduction in ductility when lead is present offers excellent malleability.

    Industrial applications of Brass.

    1.Security hardware and ironmongery.

    2.Ornamental door furniture.

    3.Handrails and balustrades.

    4.Electrical components.

    5. Decorative and protective finishes.

    6.Used in plumbing.

    7.Making of musical instruments.

    8.In the manufacturing of locks, gears, bearings, valves and braces etc.
